4 Claims.

cated, which may be produced at comparatively small expense for labor and materials, and which will provide a suitable support for the'cushioning 15 material with which a device of this character must be provided, and which is adapted to be readily bent into curved form without distortion.

I accomplish these objectsby providing a sec-.

tion of spirally coiled wire which is 'tretched to 20 a suitable extent and pressed into a flattened for:

mation, so that all the coils will be approximately in a plane, with adjacent segmental portions overlapping, then clampinga continuous metal bead to opposite intermediate portions of the coils in 25 tangential relation thereto and in parallel rela-' tion to each other, then supplying a suitable covering and cushioning material thereto and then a bending the strip thus provided into channel form. For a more complete disclosure of my invention, 30 reference is now made to the following specification, in connection with the accompanying drawings, in-which:

Fig. 1 is a side elevation of a finished channel 35- o! the type described, installed in a window cas- Flgs. 2, 3, and 4 are views illustrating different steps-in the formation of a channel core embodyi'ng my invention.

Figs. 5 and 6 are detail views of portions thereof. Figs. 7 and 8 illustrate in plan and side elevational views, a form of apparatus which may be employed inproducing the article by means of the method herein disclosed and 45 Figs. 9 and 10 are detail views, on an enlarged scale, at line X-X of Fig.8. In acorda'nce with my invention, I first provide a wire coil a, as illustrated in Fig. 2, which may be termed in the usual way by winding the wire on 50 a cylindrical mandrel, the type of wire employed being preferably round, as shown, although a flat wire of ribbon type may be employed in lieu there- 1 of within the scope of my invention. Said wire coil will then be stretched to a suit- -56 able'extentand the'n flattened, so that the coils lie in approximately the same plane, with adjacent segmental portions thereof overlapping, iorming a substantially flat elongated strip, and then securing the coils in this position by a pair of U-form clips or beads 12' which'extend continu 5 ously with the strip thus. formed and are clamped to the coil segments at each edge of the strip in tangential relation to the coil portions which do not overlap, as shown in Fig. 3.

In Figs-7 to 10 a type of apparatus is shown 10 which may be employed in performing the above described operation, and in which the coiled wire a is shown as fed down a tube I! which opens at its lower end to an endless chain ,l3,-having suitably spaced teeth II, which is driven horizonl5 tally about sprockets l5, l6 and is supported therebetween by a table Hi. The sprocket i5 is arranged directly beneath the open lower end of tube I2, in such a position that, when the chain is driven in the direction indicated by the arrow in Fig. 8, a tooth M, as it is carried upwardly and horizontally, will engage the lower coil of the wire and pull it from beneath the tube, and then, as the chain is advanced, the next tooth will pass thru this coil and engage the'next coil above and 25, pull it out in like manner, so that a series of coils will be laid horizontally with a segmental por 'tion of each 0011 overlapping a corresponding portion of the next coil in advance thereof. Converging guideway grooves 20 are provided; at each side of the course in which the coils are carried,

and elongated strips of U-form beads b are fed l therein 'in such a position that the coil portions, which extend beyond the overlapping portions, will passtherein as the coils are carried over the table by the chain. Two pairs of rolls 22 are mounted in line with the grooves 20, respectively,

in position :to clamp the beads firmly into engagement with the coils, each pair of.,rolls bein grooved to receive the beads, as shown in-Fig. 9, 4

and having teeth 24 arranged to pinch the edge portions of the bead together at suitable intervals,

as shown in Fig. 10, and in Figs. 4, 5, and 6. This 4 operation may be varied, but in any event. the beads are firmly clamped in engagement with the coils, so that they will-be securely held in the relation shown in Figs. 3 and 'l, and no movement of the coils longitudinally of the beads will be permitted.

The sprocket I6 is located in axial alignment with the shaft of the lower roll 22, and the chain passes out of engagement with the coils at a point a short distance beyond the point at which the rolls clamp the beads to the coils. A construction substantially as shown in Fig. 3 will thus be produced.

' By the next operation, the construction shown in Fig. 3 will be bent into channel form, to form the core of the channel as shown in Fig. 4, so that the beads b will form the edges of the side of the channel, but, before this shaping operation is performed, a suitable cushioning material will be placed on what is to be the inner side of the channel and the entire core will preferably be enclosed in a textile covering d.

The shaping operation of the strip shown in Fig. 3 into channel form, and the operation of covering the core thus formed with cushioning material, may be performed by the well known means commonly employed in the production of similar devices.

It will be apparent that the construction shown may be readily bent to conform to curved window frames, as indicated in Fig. 1, the only part of the core which is actually bent being the edge bead, which may be bent without substantial distortion.

While the form of edge bead shown is considered the most practical of any form of which I am aware it will be apparent that other means for providing a continuous edge may be employed, as for example, a metal strip may be secured to the coils by spot welding, but such an arrangement would be less desirable than tha shown.

I claim:

1. A window glass channel having a channel shaped metal core composed of a continuous wire formed into a series of coils having oppositely disposed segmental portions thereof arranged approximately in the same plane with the corresponding segmental portion of each coil overlapping the opposite segmental portion of the next adjacent coil and means engaged with the intermediate portions of said coils for securing the same in fixed relation.

2. A window glass channel having a channel 5 shaped metal core composed of a continuous wire formed into a series of coils having oppositely disposed segmental portions thereof arranged approximately in the same plane with the corresponding segmental portion of each coil overlapping the opposite segmental portion of the next adjacent coil and a continuous stay band engaged with the coil portions intermediate said segmental portions at each side of the core.

3. A window glass channel having a channel shaped metal core composed of a continuous wire formed into a series of coils having oppositely disposed segmental portions thereof arranged approximately in the same plane with the corresponding segmental portion of each coil overlapping the opposite segmental portion of the next adjacent coil and a continuous bead held in clamping engagement with the coil per-- tions intermediate said segmental portions at each side of the core.

4. A window glass channel having a channel shaped metal core composed of a continuous wire formed into a series of coils having oppositely disposed segmental portions thereof arranged approximately in the same plane with the corresponding segmental portion of each coil overlapping the opposite segmental portion of the next adjacent coil and a continuous U-form bead clamped about the coil portions intermediate said segmental portions at each side of the core, to form continuous edges therefor.
